+
+### Overview
+
+This is a multi-label, multi-class linear classifer for emotions that works with [sentence-transformers/all-MiniLM-L12-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L12-v2), having been trained on the [go_emotions](https://huggingface.co/datasets/go_emotions) dataset.
+
+### Labels
+
+The 28 labels from the [go_emotions](https://huggingface.co/datasets/go_emotions) dataset are:
+```
+['admiration', 'amusement', 'anger', 'annoyance', 'approval', 'caring', 'confusion', 'curiosity', 'desire', 'disappointment', 'disapproval', 'disgust', 'embarrassment', 'excitement', 'fear', 'gratitude', 'grief', 'joy', 'love', 'nervousness', 'optimism', 'pride', 'realization', 'relief', 'remorse', 'sadness', 'surprise', 'neutral']
+```
+
+### Metrics (exact match of labels per item)
+
+This is a multi-label, multi-class dataset, so each label is effectively a separate binary classification. Evaluating across all labels per item in the go_emotions test split the metrics are shown below.
+
+Optimising the threshold per label to optimise the F1 metric, the metrics (evaluated on the go_emotions test split) are:
+
+- Precision: 0.378
+- Recall: 0.438
+- F1: 0.394
+
+Weighted by the relative support of each label in the dataset, this is:
+
+- Precision: 0.424
+- Recall: 0.590
+- F1: 0.481
+
+Using a fixed threshold of 0.5 to convert the scores to binary predictions for each label, the metrics (evaluated on the go_emotions test split, and unweighted by support) are:
+
+- Precision: 0.568
+- Recall: 0.214
+- F1: 0.260
+
+### Metrics (per-label)
+
+This is a multi-label, multi-class dataset, so each label is effectively a separate binary classification and metrics are better measured per label.
+
+Optimising the threshold per label to optimise the F1 metric, the metrics (evaluated on the go_emotions test split) are:
+|                |    f1 | precision | recall | support | threshold |

+The thesholds are stored in `thresholds.json`.
+
+### Use with ONNXRuntime
+
+The input to the model is called `logits`, and there is one output per label. Each output produces a 2d array, with 1 row per input row, and each row having 2 columns - the first being a proba output for the negative case, and the second being a proba output for the positive case.
+
+```python
+# Assuming you have embeddings from all-MiniLM-L12-v2 for the input sentences
+# E.g. produced from sentence-transformers such as:
+#      huggingface.co/sentence-transformers/all-MiniLM-L12-v2
+#      or from an ONNX version E.g. huggingface.co/Xenova/all-MiniLM-L12-v2
+
+print(embeddings.shape)  # E.g. a batch of 1 sentence
+> (1, 384)
+
+import onnxruntime as ort
+
+sess = ort.InferenceSession("path_to_model_dot_onnx", providers=['CPUExecutionProvider'])
+
+outputs = [o.name for o in sess.get_outputs()]  # list of labels, in the order of the outputs
+preds_onnx = sess.run(_outputs, {'logits': embeddings})
+# preds_onnx is a list with 28 entries, one per label,
+# each with a numpy array of shape (1, 2) given the input was a batch of 1
+
+print(outputs[0])
+> surprise
+print(preds_onnx[0])
+> array([[0.97136074, 0.02863926]], dtype=float32)
+
+# load thresholds.json and use that (per label) to convert the positive case score to a binary prediction 
+```
+
+### Commentary on the dataset
+
+Some labels (E.g. gratitude) when considered independently perform very strongly, whilst others (E.g. relief) perform very poorly.
+
+This is a challenging dataset. Labels such as relief do have much fewer examples in the training data (less than 100 out of the 40k+, and only 11 in the test split).
+
+But there is also some ambiguity and/or labelling errors visible in the training data of go_emotions that is suspected to constrain the performance. Data cleaning on the dataset to reduce some of the mistakes, ambiguity, conflicts and duplication in the labelling would produce a higher performing model.
